It's happened to all of us: a tired fellow passenger on a cramped flight nods off onto your shoulder. But what do you do? Wait for the person to wake up? Gently nudge them until they wake up? Or just let them go on sleeping as you guzzle rum and cokes until you pass out on them?

When someone conked out on Steve Cullum's lap during a recent East Coast trip, he turned the whole thing into a hilarious little film called "Awkward Flight." (See below.)

Here's how Cullum describes the situation:

"This lady was totally out of it. As soon as she sat down, she started falling asleep, and it only got worse as the flight continued. I tried lifting her up, shaking her, and startling her, but it seemed like nothing was going to work. So, I thought it would be fun to get some of it on video to share with family and friends. Then she finally moved... Only to find someone else for the last part of the flight. Ha!"

Cullum says he didn't try to notify flight attendants about the sleeping woman because there was turbulence and attendants weren't allowed to get up unless it was a medical emergency. (I guess being seriously sleepy doesn't count.)

In a similar vein, check out the video below Awkward Flight, where comedians prank subway riders in New York City by falling asleep on them. This sort of thing never never seems to get tired! (Hardee-har-har…)
